MOVABLE FEED-ROLL CARRIER.

Patented Jan. 18, 1916.

To all whom it may concern:

Be it known that 1, CHARLES S. BATDORF, a citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Movable Feed-Boll Car.- riers, of which the following is a full, clear, and exact description.

My invention relates to wrapper feeding mechanism for article wrapping machines, such for example, as that illustrated in my Patent No. 998,830 granted July 25, 1911, the. object of the invention being to provide an improved construction and arrangement of feeding rolls, inrluding means of mounting'the presser roll, whereby the wrapper strip may be fed when the presser roll is in one position and whereby the presser roll may be readily moved free of the cooperating roll, to facilitate the threading or removal of the strip.

A further object of the invention is to provide improved means for straightening the wrapper strip or taking out the curl due to the fact that the wrapper supply is usually convenientlv arranged in a roll, such rolling of the strip necessarilyv results. in causing the same to curl when freed. from the roll.

With these objects in view, the invention consists in the construction and arrangements of parts, a preferred embodimentof which is illustrated in the accompanying drawings, in which,-

Figure 1 is a plan view of so much of a coin wrapping machine, showing the invention in conjunction therewith as is neces sary to illustrate the same. Fig. 2 is aside elevation of the parts shown in Fig. 1. Fig. 3 is a detail view of an eccentric hub and operating arm therewith, in which the shaft of the presser 33011 is operably mounted. Fig. is an edge view of the part shown in Fig. 8. Fig. 5 is a detail view showingthe manner of mounting the opposite end of the presser roll shaft. big. 6 is a view of the parts shown in Fig. 5, looking from the right. Fig. 7 is a sectional view on the line 7 7, Fig 1 of the wrapper strip straightenmg device. j a

In the drawings, .11 indicates fragmentary parts of the side frames of the machine.

2 indicates a frame member upon which the wrapper roll support 3 is adjustably mounted by means of a set screw 4, whereby said roll support may be adjusted to aline properly with the feed rolls. Rotatably mounted in open bearings in arms 5 extending forwardly fromthe wrapper roll support is a wrapper straightening device, comprising a transverse bar v(3,preferably constructed vwith a fiat upper surface 7, Fig. 7 presenting abrupt corners. 8+9 to the passage of the wrapper strip 10 thereover. On the straightening bar 6 is mounted a presserplate 11 secured to said bar by means of the bolts 12 and nuts 18, which bolts extend through to the opposite sideof the bar 6 and their lower ends are connected by transverse bar 14 secured thereto by the nuts 15. Surrounding the bolts 12 and be tween the straightening bar and the bar 14: are springs 16 which serve to hold the presser bar 11 with more or less pressure against the straightening bar 6, thereby causing the wrapper strip to be held firmly against said straightening bar. The straightener bar 6 together with the parts carried thereby is held in adjusted position by means of spring plates 6 secured to the arms 5 by screws 5, the ends of said plates being pressed heavily against the extremities of said bar 6 opposite the open bearings respectively in the arms 5 whereby the bar 6 is held stationary against the drag of the strip thereon. With the straightening bar in the position indicated in Fig. 2, comparatively little straightening effect is produced upon the wrapper strip. If however,

the upper side of the straightening bar be tilted toward the wrapper roll, the outer edge 9 of the said bar in conjunction with the presser bar 11, which serves to hold the strip firmly against the upper side of the straightening bar serves to straighten the strip by removing the curl thereof due to its previouslyrolled condition. The straightening bar is provided with a knurled head 17, by which said bar may be manually tilted to any desired position determined by the amount of curl of the strip and by the stiflness of the material thereof. It is evident that as the supply roll is reduced in diameter by reason of the feeding of. the wrapper strip, the curl of the strip will become more pronounced. It will therefore, be necessary to tilt the straightening bar to a greater de ree toward said supply roll,

in order to straighten said strip as the supnlV roll is reduced. a V

r In the side frame 1is journaled a feed roll shaft 18 carrying the main feed roll 19, and mounted adjacent said roll 19 is a presser roll. 20 carried, by the shaft 21. The lower.

end of the shaft 21 as viewed in Fig. 1 is mounted in an eccentric aperture 22 of an eccentric hub 23 journaled in the side frame 1,.said hub having a manually operable arm 24, whereby said shaft may be shifted to carry the presser roll into and out of engagement with the feed roll 19. The opposite end of the shaft 21 is mountedby a universal joint 25 in the hub 26 of the pinion 27, said hub 26 being journaled in the adjacent side frame 1. The pinion 27. is engaged by gear 28 which in turn may be con nected with any suitable formof rack arm as illustrated in my patent above referred 'T to, whereby said feed roll 19 and the presser 25 roll 20 may be actuated to feed the strip. To draw the presser roll 20 firmly against the feed roll 19 suitable springs 29 are interposed between the shafts 18 and 2lcarrying said rolls respectively. On the side a 30 frame 1 adjacent the eccentric operating arm 24c is an adjustable stop pin 24 by which the degree of pressure exerted by the presser roll 20 upon the strip fed over the roll 19 may be regulated according to the ferred embodiment of my invention, it is understood that the same may be altered in 7 detail and relative arrangement of parts combination with a wrapper supply of a within the scope'of the appended claims;

What I claim is: 1. In a wrapper feeding mechanism, the combination with. a wrapper supply of a i 1 feed roll and presser roll cooperatingtherewith, a shaft for said presser roll a rotatable support for one end of said shaft, a universal joint between said support and said shaft, a rotatable support for the opposite end of said shaft, upon which said shaft is eccentrically mounted and means for rotating thelatter support to move said presser roll into and out of engagement'with said feed roll.

2. In a wrapper feeding mechanism, the

feed roll and a presser roll cooperating therewith, a shaft for said presser roll, a rotatable support for one end of said shaft, a universal joint connecting said support and shaft, a pinion on saidsupport, a gear fixed to said feed roll and meshing with said pinion, means for operating said gear to rotate *said feed roll and presser roll respectively,
